Question

我有一个已发布并在服务器上工作的Web应用程序。我有 aspx 文件，但我没有 .vb 文件。我需要在应用程序中编辑单页。如何访问 .vb 文件？或者更好地说我如何在应用程序中编辑我想要的部分？

修改这是我的aspx文件：

<%@ page language="VB" autoeventwireup="false" inherits="UrunRapor, App_Web_hfev-r-q" %>

Answer 1

发布站点时，编译的版本将在服务器上发布，而不是代码文件。您需要反汇编程序/反编译器来反编译dll文件。其中一些是

.Net Reflecter
ILSpy （免费）
Dot Peek （免费）

Answer 2

您可以做的是更改ASPX，例如，而不是：

<%@ Page Language="C#" CodeBehind="MyPage.aspx.cs" Inherits="MyNamespace.MyPage" %>

您可以这样更改：

<%@ Page Language="C#" Inherits="MyOtherNamespace.MyNewPage" %>

将新行为写入新的MyOtherNamespace.MyNewPage类（应该至少从System.Web.UI.Page派生），您可以将其放入bin目录中部署的任何.DLL程序集中。

您还可以从原始页面（仅引用原始程序集）派生此新类，而不是仅从System.Web.UI.Page派生，如果派生是您的选项，具体取决于您需要执行的更改

否则，您将不得不使用.NET Reflector或ILSpy等工具重建原始代码来构建这个新类，但至少，您不必触及现有的编译程序集。

Answer 3

您可以尝试使用ilasm对其进行反汇编并直接编辑IL，但我认为现实中您将很难在没有源的情况下进行任何更改。 .cs文件是源文件。只有已编译的IL文件才能在发布的站点上使用。您将需要找出谁发布它并与他们谈论获取源。

缺少已发布的ASP.NET应用程序的源代码
